Abstract
A test stand assembly includes an electric machine () for driving and/or loading a test object (), which is connected by a connecting shaft () having an adapter flange () to the electric machine (). The assembly has a constant, predetermined moment of inertia, and the mass and the moment of inertia of the adapter flange () are selected in such a manner that the resonant frequency of the system formed of test object (), adapter flange (), connecting flange (), and electric machine () for driving and/or loading the test object () lies between the idle frequency and the partial load frequency of the test object ().
